Cooler Master Mid Tower Micro-ATX/ATX Computer Case (Midnight Black)

The Cooler Master NSE-400-KKN2 is a mid tower computer case that focuses on steady airflow, straightforward installation, and long-term reliability. It ships with a fully meshed front panel that pulls cool air directly across your hardware, and two 120 mm fans are already in place so you can power on right after the build. If you plan to push your system harder, the interior has mounts for up to eight fans in total, letting you scale ventilation as your components grow hotter or more power-hungry.

Inside, the chassis accepts Micro-ATX or ATX motherboards, giving new builders and upgraders equal flexibility. A graphics card measuring up to 12.6 inches slides in without a struggle, while a CPU cooler that reaches 6.4 inches tall has room to spare. These clearances make the case a practical choice for a gaming rig, a workstation, or a mixed-use system that juggles both play and productivity.

Storage support is generous. Seven drive trays fit traditional 3.5-inch hard drives for bulk media or backups, and three dedicated locations hold 2.5-inch SSDs for the operating system and frequently used applications. This layout lets content creators, gamers, and home-office users keep large libraries close at hand without adding external enclosures.

If you prefer liquid cooling, the NSE-400-KKN2 accepts a 240 mm radiator at the top or side and a 120 mm radiator at the rear. These mounting points open the door to quiet, high-performance loops that tame modern processors and high-end graphics cards without filling the case with additional fans.

Day-to-day use is just as practical. Dual USB 3.0 ports on the front panel handle fast file transfers and peripheral charging, while three removable dust filters capture debris before it settles on your components. The exterior comes in Midnight Black, a finish that looks at home under a gaming desk, in a studio, or beside a living-room entertainment center.
